Thunderbird Backup and restore

Hello, please excuse my bad english. My mother tongue is German.

      I would like to submit a request to the development team.           I have been using Thunderbird for a long time and am very satisfied with it.

      I save my communication, that means my outgoing and incoming emails always in subfolders.           This creates an archive of my emails.

      It would be a huge data loss for me if suddenly something with the program does not work anymore.

      I therefore wish a new feature in the Thunderbird, which makes it possible to backup (and restore) the email communication.

Thank you

That add-on offers backup and restore as one of it’s features.
